Difference Between XHTML and HTML

Difference Between XHTML and HTML 

 
HTML and XHTML are completely differ from each other in document structure,elements and attribute format.
 

XHTML

 
->XHTML is proposed by W3C Recommendation in 2000.

->It is developed by W3C(World Wide Web Consortium).

->XHTML files are saved with .xhtml, .xht, .xml , .html and .htm extension.

->XHTML is an XML application.
 
Eg:
  1. <html>  
  2.     <head>  
  3.         <title>This is an XHTML page </title>  
  4.     </head>  
  5.     <body>  
  6.         <p> This is my  first XHTML page </p>  
  7.     </body>  
  8. </html>  
 As shown in the above example, there is both tag ie. starting tag as well as ending tag (ie <p> and </p>). That means it follows all principles.
 

HTML

 
->HTML is proposed by Tin-Berners-Lee in 1987.
 
->HTML is developed by W3C and WHATWG.
 
->HTML files are saved with .html and .htm extension.
 
->HTML is an SGML (Standard Generalized Markup Language) application.
 
Eg:
  1. <html>  
  2.     <head>  
  3.         <title>This is an XHTML page </title>  
  4.     </head>  
  5.     <body>  
  6.         <p> This is my  first XHTML page   
  7.         </body>  
  8.     </html>  
 As shown in the above example, there is no ending tag ie </p> that means it doesn't follow the rule. That's why we need the XHTML instead of HTML.
